drawings, the numeral 1 indicates a strip of cheap short fibre paper as, for instance, ex-

. of this ring, and the out-er face of the strip is coated with adhesive to firmly attach the coils together. In the embodiment illustrated the rings are of circular outline. It is to be understood, however, that the ring may be oval or even angular in outline as, for instance, rectangular or hexagonal, without *Referring now more specifically to the adjacent the crimped departing from the spirit of the invention.

The numeral 3 indicates a strip of a tough fibrous grade of paper, as for instance, craft paper which has a long fibre and is not so apt to crack under the strain of crimping. The strip 3, as illustrated, is wider than the strip 1 and is coiled around the ring 4 formed of the strip 1 into a ring 5, the strip 3 being coiled twice around the ring 4, and the coiling being started at a point 6, preferably diametrically opposite the ends of the strip 1 in the ring 4, so that the joint of one ring does not lie at the same part of the circumferences as that of the other. One edge 7 of the craft paper strip is laid flush with an edge, as 8, of the ring 4 so that the multiple-ply or laminated ring 5 extends beyond the opposite end of the ring 4, as clearly illustrated at 9 in Figs. 3 and 4.

In the present embodiment of the invention, before the craft paper strip 3 is coiled around the ring 4, that face of the craft paper strip which is to be the inner face of the coils, is treated with sizing as, for instance, animal glue, which is permitted to become dry before the craft paper strip is utilized to form the coil. The full width of the craft paper strip is so treated, in the present embodiment, and just before the coiling thereof is effected that part of the width of the strip which registers with the first ring 4 is moistened. to as to provide an adhesive face or coat which will stick to the outer face of the ring 4 when coiled therearound, and so that the plies of the ring of craft paper will be secured to each other for a part of the width of the craft paper ring. That part of the width of the multiple-ply craft aper ring which extends beyond the end 0 the ring 4, as indicated at 9 in Fig. 3, will have the unmoistened and consequently dry sizing on its inner face and between the plies thereof. Thus the dry sizing has a nonaclherent outer face between the plies of the extended portion 9 of the craft paper ring. In Fig. 3 the coat of sizing is indicated by the stippling, the dotted line 90 indicating the meeting line of the dry and moist sections.

The coiling of the strips 1 and 3 may be effected on a rotary cylindrical mandrel, or form, and the strips supplied to the mandrel by any suitable feed device. In the embodiment illustrated, however, the craft paper strip 3 is yieldingly pressed laterally as it is fed so that its edge, as 7, lies in predetermined relation to the edge 8 of the ring 4 on which it is coiled. As illustrated, the craft paper strip 3 lies in a guide channel 10 in a strip support 11. A spring-pressed I guide plate 12 ieldingly presses against one edge of the strip 3 so that the opposite edge is pressed against the wall of the channel and thereby in line with the edge 8 of the rim 4.

Referring to Fig. 3, the inner edge 13 of the first multiple-ply ring forms a shoulder in tercepting the wall of the second multipleply ring 5 or craft paper, and this shoulder provides a continuous support for a head, which may be a domed head, as illustrated at 14, Fig. 10, or a flat head as indicated at 15, Fig. 12. In the embodiment of the box illustrated a flat paper disk or additional head 16 is disposed on the shoulder 13 beneath the domed head 14, these parts being disposed to be held in place by the crimped portion of the ring, as will appear.

By the provision of the multiple-ply ring 5 with sizing between the plies, as described, an article is formed which lends itself readily to the crimping operation. The sizing on the extension to be crimped, is dry, so that the plies at this part are normally non-adherent. This sizing is then softened so as to be rendered adherent and thereupon the crimping operation is effected, the edges of the plies or laminae of the ring 5 being folded inwardly or curled to form a head, or crimp, 17, which will press down upon the head 14 and maintain it in position, all as indicated diagrammatically in Figs. 12 and 14. The softening of the sizing is effected, in the present embodiment, by heat ing the extended portion 9 of the multipleply ring of craft paper. This may be conveniently done by providing a heated crimping die and bringing the sized extended portion 9 of the ring 5 into contact with the die and letting it remain in contact therewith for a short time prior to efi'ecting crimping. Thus the unmoistened sizing between the plies of the extended portion is softened and in condition to fasten together the plies of the extended portion of the ring 5 by causing them to adhere to each other. By the crimping operation the plies are turned inwardly and they readily, as it were, fold and slide upon each other, while the sizing is soft, so that the crimping operation is effective and neat. After the crimping operation the crimped parts are pern'iitted to cool and this effects the hardening, or setting, of the sizing which thereby retains and holds the folded plies in crimped form.

Whereas the multiple-ply ring of craft paper with sizing between the plies, as described, lends itself readily to the crimping operation hereinbefore set forth, it is desirable in many instances to cover the craft paper ring with ornamental material and to bind the edges of the plies of craft paper together prior to and during the crimping operation. To this end a binding strip 20 (Fig. 5) is applied on the outside of the multiple-ply ring 5, the edges of this binding strip extending beyond each of the opposite edges of the craft paper ring. This binding strip may be of very thin material, thinner than the card middle strip or the craft paper, and may be printed, coated or otherwise ornamented so as to give a desired ornamental surface to the ring 5. In the present embodiment the binding strip is a gold strip, that is to say, one face has a golden appearance. Its opposite surface is given a thin coat of glue in order that it may adhere to the ring 5. The strip 20 having been coiled once around the ring 5 and cut off, the opposite ends of the resultant gold ring are folded across the multiple-ply edges of the assembled rings 4 and 5 and into and against the inner surface of said rings, as

illustrated at 21 and 22, Fig. 7. In effecting the folding across the edge of the extension 9 of the multiple-ply [ring 5, a roller 23, Fig. 9, is employed which. is yieldingly pressed towards the edge of the ring during the folding operation and thereby makes the fold of the binding strip closely conform to the edge of this ring even though this edge be somewhat irregular. It is to be understood that the coiling of the strips 1, 3, and 20 into rings is effected by rotating the mandrel or form, and that the folding of the gold strip 20 at 21 .is effected by the roller 23, as the mandrel rotates and as this strip is Wound around the ring 5. Proper pressing rollers may be employed to assure that the coiling shall be smooth and'tight. The provision of the folded thin binding s-rip 20 not only serves to ornament the outer face of the craft paper ring 5 but surrounds the drysized end of the craft paper ring and prevents access of extraneous matter as dust, atmospheric moisture, etc. to the sizing between the plies. The paper of which the binding strip 20 is composed, however, is thin and does not interfere with effective crimping. The adhesive for the binding strip is of relatively thin. consistency and this and the thin binding paper 20 at the c-rimped edge merge with and form part of the crimp when the sizing is softened by heating the ring at its bound edge.

By the construction herewith described there is provided a crimped paper'ring in which the crimp is set by the sizing, the sizing becoming hard and stiff and'thereby setting the paper .in crimped form. By'the use of relatively thin paper coiled into ring form as explained, the ring may be made of any thickness desired and may be efli ciently crimped.

In Fig. 12 of the drawing is illustrated a box in which the base 24 and the lid 25 are made in accordance with the method hereinbefore described. Thebox illustrated is designed to hold face powder and is provided on its interior with a cover 26 of imperforate frangible fabric, such as thin paper. The cover 26 at its edge is secured to an interior multiple-ply flange 27 which conforms to the shape of the inner wall of the base 24 and is adhesively secured to said inner wall. Like- 28 of the rollers deeper than the thickness referred to. In this above construction and in the box, the lid 25 is removed and the 7 cover 26 broken, as by pressing a finger against it. i

To fold the projecting edges of the binding strip 20 across the opposite edges of the multiple-ply rings, or body-ring fingers, as, 75

for instance, rollers having square shoulders 28, are preferably employed. These rollers are illustrated at 23 in Fig. 9. It will be perceived that the respective projecting edges of strip 20, when folded across the adjacent edges of the multiple-ply ring, tend to and usually do gather or pucker on account of the decreased diameter assumed by the ex-- treme edges of strip 20 when in ring form. On account of the folded edges ofthe binding-ring there is a tendency for the folded edges to pop or spring from the opposite edges of the multiple-ply ring. To avoid this possible separation, the edges of strip 20 are closely against the opposite edges of t 1e multiple-ply ring for the full thickness of the edges of the multiple-ply ring, the shoulders 23 being as deep or a little Wise the folded edges lie in close contact with the edges of the multiple-ply, ring and the folded material, due to the puckers, takes up a position pointing inwardly of the multiple-ply ring, this wise, each folded edge of strip 20 maintains its folded condition close ,to the edges of the multiple-ply rings, so as to be readily folded into and pressed against the inner faces of the multiple-ply rings by subsequently operating folding elements, as the disk-folders 30 and 31 which move axially of the multiple-ply rings, into and out of op posite ends of the same, the perimeter of such disk-folders closely fitting he inner diameters of the multiple-ply ring at its respective opposite ends. It will be understood that after the edges of strip 20 are folded by the rollers 23 as the multiple-pl ring rotates with the mandrel, the disk fol ers 30 and 31 move ax-- ially, the perimeters thereof wiping the folds into the paper ring and against the inner wall thereof.

Preferably the disks 30 and 31 are so mounted as to rotate as the paper ring rotates, and the wiping of the folds into the paper ring occurs while the paper ring and said disk are rotating.

Thus by the above construction are accomplished among others the objects to which reference has hereinbefore been made.

As many changescould be made in the many apparently widely different embodiments of this invention could be made without departing from gather or puckers in the 85 ressed 90 as indicated at 29, Fig. 9. In 100 limiting sense.
